SPARRING siblings from Greenock are set to pack a punch this summer in front of an audience of 4,000 people. Talented pair Noah and Jonah Waddell, who live in John Street, have been invited to attend the Yokkao Supershowdown event at the Macron Stadium in Bolton on July 31. The boxing brothers will grapple with young Thai boxing fighters from all over the UK at the prestigious event. Their proud dad Mark, who also coaches his sons, says being invited to appear at the flagship Muay Thai boxing showcase is a big achievement for the boys. He told the Tele: The boys have got to a really good level.
